%X In several areas in Indonesia, it is often found that community groundwater and river water during the dry or rainy season does not meet the quality standards for safe drinking water, and in certain locations the water is even unfit for consumption because it is turbid and mixed with mud. Clean water is very important for human life. This research aims to create a water purification tool using coagulation and adsorption methods, determine the effect of these two methods, develop LKPD, carry out feasibility tests and determine students' responses to the media being developed.This research uses the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The water purification tool and learning worksheet developed were tested on 30 class XI students. Validity tests were carried out on the water purification equipment and LKPD based on the assessment of material experts, media experts and student responses. The LKPD research instrument for water purification using the coagulation and adsorption method is a validation sheet using a Likert scale which includes content feasibility aspects, presentation feasibility aspects, linguistic aspects, green chemistry aspects and graphic aspects. Aspects of suitability of the tool, practical aspects of the tool, and aspects of usefulness. The research results based on expert assessment obtained a percentage of 0.92% for the appropriateness aspect of the content, 0.90% for the presentation aspect, 0.91 for thelinguistic aspect, and 0.92% for the green chemistry aspect, 0.94 for the graphic aspect. Meanwhile, student responses received an overall average percentage of 82% with the "very good" category. Thus, it can be concluded that the water purification tool and LKPD for water purification using the coagulation and adsorption method are declared valid and suitable for use in the learning process.

%O Pada beberapa daerah di Indonesia sering ditemukan air tanah dan air sungai masyarakat pada musim kemarau atau hujan tidak memenuhi baku mutu air minum yang aman, bahkan di lokasi tertentu airnya tidak layak dikonsumsi karena kekeruhan dan bercampur lumpur. Air bersih sangat penting bagi kehidupan manusia. Penelitian ini bertujuan untuk membuat alat penjernihan air dengan metode koagulasi dan adsorpsi, mengetahui pengaruh dari kedua metode tersebut, mengembangkan LKPD, melakukan uji kelayakan dan mengetahui respon peserta didik terhadap media yang dikembangkan. Penelitian ini menggunakan model ADDIE (Analysis, Design, Development, Implementation, and Evaluation). Alat penjernihan air dan LKPD pembelajaran yang dikembangkan di uji coba kepada 30 peserta didik kelas XI. Uji validitas dilakukan pada alat penjernihan air dan LKPD berdasarkan penilaian ahli materi, ahli media dan respon peserta didik. Instrument penelitian LKPD penjernihan air metode koagulasi dan adsorpsi berupa lembar- lembar validasi menggunakan skala likert yang meliputi aspek kelayakan isi, aspek kelayakan penyajian, aspek kebahasaan, aspek green chemistry dan aspek kegrafikan. Aspek kelayakan alat, aspek kepraktisan alat, dan aspek kebermanfaatan. Hasil penelitian berdasarkan penilaian ahli mendapat persentase 0.92% untuk aspek kelayakan isi, 0.90% untuk aspek penyajian, 0.91% untuk aspek kebahasaan, dan 0.92% untuk aspek green chemistry, 0.94% untuk aspek kegrafikan. Sedangkan untuk respon peserta didik mendapatkan persentase rata-rata keseluruhan sebesar 82% dengan katerori “sangat baik”. Dengan demikian, dapat disimpulkan bahwa alat penjernihan air dan LKPD penjernihan air dengan metode koagulasi dan adsorpsi dinyatakan valid dan layak untuk digunakan dalam proses pembelajaran.
